2 Claims. 1

This invention relates to cosmetic products, particularly lipsticks andperfume sticks, and has for its main object to provide a lipstick whichmore color may be contained than in lipsticks at present in use orproposed, and also to provide perfume sticks which will have moreperfume content than such devices now known, and still both of thesedevices will have the same, or even superior desirable qualities as toappearance, storage, and use, as those used at present.

Lipsticks, and also perfume sticks, used at present, are based oncertain compositions, which must resist the summer heat as well aswinter cold, and remain during such changes of tem perature,approximately of the same hardness, and of the same rubbing quality, andstill they should take as much color, or perfume material, as possiblewhile retaining said qualities of hard ness and application, and theyalso should show a uniform homogeneous appearance on the skin.

There are many other requirements and characteristics desired incompositions indicated for the purposes mentioned, and the presentlipstick and perfume stick mixtures, well known in this art, as a rule,substantially answer uch requirements.

T e r en os tic t c s l e i tisk and r u e sti k an an other os e c istic form, are made of mixtures of waxes, fats, emollients, and oils,forming the base for the product;

Certain specific colorsare added to the base, in the case of lipsticks,or concentrated essential perfume oils, for the perfume sticks. Theresult-v ing stick is a homogeneous compound of some predetermineddesired hardness, and adapted to withstand the mentioned high or lowtemperatures.

The composition, and the method of production, of lipsticks, or perfumesticks, at the present time, will greatly limit the amount of color tobe introduced into the lipstick and the amount of perfume material to beplaced in a perfume stick. This is mainly due to the fact that both, thecolor and the perfume material, must be added to the mentioned basiccompound or mixture in liquid solutions, for instance, for the lipsticka color mixture in castor oil. If too much of such oil solution of coloris added to the mentioned base mixture of the lipstick, the same willbecome too soft and can not be used in summer temperatures. The samecondition applies to the perfume stick, as the perfume extract must beadded in a liquid solution, and only a very limited amountcan beintroduced into the stick, in order not to make it too soft. The reasonswhy the 2 desired colors, or perfume extracts, cannot be added in anyother form than of an oil, or other liquid, solution, to the finalcosmetic sticks, are well known to those versed in this art, and thereis no need to further enlarge on them.

My invention mainly aims to produce. lipsticks of the desired hardness,staying, wearing and application qualities, and still adapted to receivemore of the selected attractive colors, in a desired homogeneousproduct, of the desired rubbing and application qualities, than is thecase with-lipsticks used at present. 7

Similarly, with respect to the perfume sticks, my invention mainly aimsto provide a stick of the mentioned desired qualities, which will contain a greater amount of perfume material than could be added to perfumesticks now in use, and still retain the hardness, staying, and rubbingqualities desired in a perfume stick, and also to provide a perfumestick which will be substantially colorless in a rubbing application.

With the mentioned, and other, objects'in view, my invention mainlyconsists in providing an outer hollow jacket, covering or shell for thelipstick or perfume stick, said shell being substantially of the samematerial as such lipsticks or perfume sticks are made at present, so asto have the same staying, wearing, and application qualities. Theseshells I then fill with my novel color or perfume mixture, which alsowill have the desirable rubbing, application, and appearance qualities,but, which will contain a much larger percentage of color, respectivelyperfume material, than the shell. Upon the application of my novellipstick or perfume stick, the outer shell will be rubbed, like usual,and, obviously, my novel inner filling will rub still easier, beingsofter in consistency, for the reasons explained hereinbefore, and wellknownto those experts versed in this art. The outer and inner materialsof my improved lipstick or perfume stick will also be adapted tohomogeneously mix with each other u on the usual pplication of suchsticks by rubbing an end thereof on the skin or on a desired otherobject, and will produce a coating on the skin, or on another object,which will have a greatly superior color effect, in the case of thelipstick, and a higher perfume effect, in the case of the perfume stick.

I also attach drawings to this specification, to illustrate, in adiagrammatical manner, the construction of my novel lipstick or perfumestick, and one method of manufacturing the same, and in said drawings: ao

Fig. 1 is an elevational view of my novel lipstick, a portion of thesame being broken away, and

Fig. 2 is a plan view thereof;

Fig. 3 illustrates a tool or die which I employ in manufacturing myimproved lipstick or cosmetic stick; and

Fig. 4 shows a portion of the die in a position after the ready lipstickjackets have been removed from the same.

In this specification, I will describe in detail the parts, composition,and methods of manufacturing, with reference to lipsticks, and it willbe obvious that a perfume stick, or any other similar cosmetic product,may be manufactured in a similar manner.

In producing my novel lipstick, I use for the shell, indicated in thedrawing by the numeral [0, a more or less standard, well-known, usualcomposition. Such present compositions for a lipstick have a basemixture, which I also use as a base for the mixture of my outer shellI0. For this base I may use, as an example, one of the following twocompositions, the parts thereof being given in percentages of weight:

' Base mixtures for the shell To this base, at present, acolor mixtureis added, for the mixture of the lipstick, and I also use a similarcolor mixture to be added to the said base for my outer shell. Thiscolor mixture may be as follows, the percentages again being forweights:

3. Color mixture for the shell Castor oil 76 Colors 24 (maximum) Thecolors used are all well known in this art, and preferably are theso-called certified D C colors, or lake colors for the lipstick. Thesecolors are known as Drug and Cosmetic colors, and usedin the manufactureof lipstick.

It. is the usual practice now to take the base mixture for lipsticks,which, as I mentioned, is similar to that I use for the shell in mydevice, as indicated hereinbefore, and take the mentioned colormixturein equal quantities, mix them, and in this manner produce the lipsticknow used. It will be seen thatv such lipstick will contain 13% colormaterial, as a maximum. It is, namely, to be understood, and is wellknown in this art, that no more than 24% to 26% color material can beintroduced in oil into the lipstick by the manufacturing methods now inuse, since over that too much oil would be carried into the lipstick,and the same would become too soft, or not sufficiently resisting thesummer heat. Indeed, usually, there 15 less than 12% color material inthe lipstick. as manufactured at present.

registering In manufacturing the outer jacket or shell for my novellipstick, I use the shell mixture or mixtures mentioned hereinbefore,being similar to the base mixtures used at present for manufacturinglipsticks, and I mix into it the mentioned color mixture-castor oil andcolor material in the proportions describedso that my shell materialwill be similar to the lipsticks as manufactured today, and will haveabout 13% of the desired color material therein.

I, however, employ a second mixture in which a much higher percentage ofcolor is included, said mixture to be used for the filling or core ofthe mentioned shell.

A few of the compositions for the filling or core portion of my novellipstick may be given as follows, the proportions again beingpercentages in weight:

Formulae for core mixtures 4. Cetyl alcohol 5 Beeswax 7 Castor oil 66Colors 22 5. Cocoa butter 7 Carnauba wax 5 Castor oil 66 Colors 22 6.Spermaceti 3 Ozokerite 5 Castor oil 69 Colors 23 7. Canauba wax 4 Castoroil '72 Colors 24 This mixture, as has been mentioned, will contain alarger percentage of colors but will be much softer and easier inreacting to higher temperatures than the material of the shell. However,when the same is filled into the shell, the resulting combination stickcan be used as a usual lipstick, the shell having the necessary hardnessand resisting quality to heat, and the shell also protecting the innercore or filling against any other atmospheric influences.

The core or inner shell is indicated in the drawing at l l, and it willbe seen that when it is desired to use my novel lipstick, a selectedend, as, for instance, the one indicated at l2, will be rubbed on thelip, and in such rubbing, the material of the shell and of the innercore will be thoroughly mixed and applied in about their proportions inthe lipstick, whereby a homogeneous coating is obtained, having strongerand more desirable color effect than the effect produced when madeentirely of the shell material, as is the case with present lipsticks.

Generally, as mentioned, I propose to employ about equal amount ofmaterial in the shell and in the core, whereby the combined applicationof the two will result in said higher color effect.

In producing my novel lipstick, I may employ a casting die, generallyindicated by the numeral l3, having a left hand part I4, and a righthand part I5, and having the registering plane surfaces IB, when placedone against the other. A plurality of half cylindrical casting recesses17 are provided in the left hand die member i4, and semi-cylindricalrecesses I8 are formed in the right hand die member I5.

I also employ a third member 59 for my die, having the depending corepins or plungers 2i), registering with the holes Ha formed by thesemicylinders l1 and [8 in the respective left hand and right handmembers of the die.

The pins 20 will be smaller in diameter than the holes l9a, so that thedifference between the two will produce the desired thickness in thewall of the shell.

The base material for the shell, with its color mixture in castor oil,will be heated to about 160 or 170 degrees Fahrenheit, and the holes190. will be filled with this molten material, up to the necessaryheight.

The upper member I9 of the die will be chilled, particularly its pins20, and these pins will be inserted into the holes lSa, whereby theshell will be formed, as will be understood, and its material will bequickly chilled. After such chilling the top member I9,-with the formpins or plungers 20, will be removed, a lower member laid flat, as, forinstance, member l4 being underneath member l5, and said right handmember l5 will be lifted off the left member l4, and then the shellremoved from the recesses I! in the lower member by pushing them outaxially.

The mentioned core mixture will be prepared, as usual for cosmeticpreparations, and well known in this art, and will be filled into theshells, whereupon my novel lipstick will be ready for use.

It will be obvious that a perfume stick may be made in an entirelysimilar mariner, having a core with considerably more concentratedperfume extracts than is the case with perfume sticks now in use.Mixtures for perfume sticks are well known, and I only use fillings ofhigher perfume extract content in the shells of usual compounds in mynovel stick.

It also will be understood that the principles of my present inventionwill be employed, in general, for cases, where a certain material is tobe applied by rubbing or smearing, and where, for any reason, it isdesired to protect thematerial to be rubbed. In such cases, my inventionmay be employed by providing an outer protecting shell, which willco-operate with the material therein, and upon rubbing, they willproduce a compound efiect.

In case of lipsticks, and similar cosmetic devices, the outer shell mayeven be employed simply to protect the inner material againstatmospheric and other influences, and said outer shell may then be madeof a character to resist such influences, and to keep the inner fillingor core fresh and substantially intact for a long time, or evenindefinitely, while permitting the use thereof, the protecting shell orjacket being of a self-consuming nature, and being rubbed away while theinner core is applied by rubbing.

While I have shown preferred embodiments of my invention, it is to beunderstood that changes and variations may be resorted to in theelements, constructions and combinations of my invention, and I reservemy rights to such changes and variations as are within the spirit ofthis specification, and the scope of the claims hereunto appended. I

What I claim as new, and want to protect by Letters Patent of the UnitedStates, is:'

1. A cosmetic stick comprising a hard outer shell and a soft inner core,said outer shell and inner core each being composed of hard and soft waxmaterials, soft oily material and cosmetic material, the soft inner corebeing composed of a smaller quantity of hard wax material and largerquantities of the soft wax, oily and cosmetic materials, respectively,than said outer shell, the quantity of cosmetic material in said outershell being a maximum of approximately 12 per cent, and the cosmeticmaterial in said innercore being substantially above 12 per cent butbelow a maximum of approximately 24 per cent.

2. A lipstick composed of hard and soft wax materials, soft oilmaterials, and coloring materials, an outer shell comprising a largerpart of said hard wax materials and smaller parts of the soft wax, oiland coloring materials, respectively, and an inner filler core for saidshell carrying a smaller part of the hard wax materials and larger partsof the soft wax, oil and coloring materials, respectively, whereby saidshell portion will act as a protector for said core portion and thesetwo portions of the lipstick may be simultaneously used by rubbing andthen produce a predetermined desired effect of a lipstick of all theingredients, said shell and said core being each composed ofsubstantially equal amounts of material by weight, the color content ofthe shell portion being substantially twelve per cent of its weight, andthe color content of the core portion being about twenty-four per centof the weight thereof.
